HENRY nenANDALL, 0E HOMER, NEW YORK, ASSIGJOR OF ONE-HALF HIS RIGHT TOWATSON HOLMES, or SAME PLACE.

IMPROVEMENT IN BLACKSMITHS BUTTERISES.

Specification forming partof Letters Patent No. 207,348, dated August27, 1878; application filed July 8, 1878.

To all whom it may concern:

Be it known that I, CRANDALL, of the town of Homer, in the'county ofCortland and State of New York, have invented certain new an d usefulImprovements in Blacksmiths Butterises; and I do hereby declare that thefollowing is a full, clear, and exact description,

thereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanyin g drawings, and to the letters of reference marked thereon,which form apart of this specification.

In the drawings, Figure 1 represents my improved butteris.withitsflputsall together, 7.

as when ready for use. Fig. 2 represents the blade andshoulder-piecc,both detached from the arm and Fig. 3 represents a view showin g the endof the socket.

The invention consists in making a detachable blade, with a shankbeveled at its front edge on opposite sides, and providing an arm with asocket slotted at its front, and the walls at each side of said slotbeveled on the inside to correspond with the bevels on the shank,serving as a guide in inserting the shank. p

A represents the blade, B the arm, and G the handle or shoulder-piece.The blade has 7 a shank, a, which fits firmly into a socket, b,

at the end of the arm B. The shank a is beveled on opposite sides at itsfront edge, and the socket b on the arm B is provided with a slotat itsfront, and at each side of said slot the walls are beveled on theinside, to correspoud withthe bevcls on the shank and serve as a guidein inserting said shank.

The advantages of having adetachable blade are readily seen. Wheneverone blade be comes dull another can place. I

Bymakingthe shank a slightly tapering be readily put in its 7 from theblade, and the socket I) to correspond, they wedge together, and thesocket holds the blade firmly without the necessity of any other deviceor attachment.

By reasonof the slot in the socketa certain amount of elasticity isimparted to the same,

. allowing the socket to spring as the shank is inserted, and firmlysecure the shank'therein. The upper .end of the arm B is cut withscrew-threads c, by meansof which and corresponding threads cut in thesocket of the shoulder-piece the arm B may be adjusted by lengthening orshortening, so as to suit the requirements of different workmen.

which I make by rounding the corners vZ-i and making the under side ofthe blade slightly" convex. By thus shaping the blade it is less likelyto draw down and out too deep into the hoof when paring it.

Havingthus described my invention, I

clai1n-- The combination, in a blacksmiths butteris, of the blade A,provided with a shank, a, beveled on opposite sides at its front edge,and v GEORGE J. MAYOUMIBER, CHARLES O. DEWEY.
